FASTENING TORQUE
The proper fastening torque differs depending on the kind
and size of the screw and the type of the material to be
fastened.
NOTE!
When fastening a screw smaller than M6, check the
fastening torque and fastening time. (Fig. 5)
X-axis (abscissa) : Fastening time (Second)
Y-axis (ordinate) : Fastening torque (Nm)
Carefully adjust the fastening torque by controlling the
trigger-squeezing force so that the screw is not damaged.
NOTE!
To avoid the reduction of the fastening torque, keep the
battery properly charged.
The fastening torque is affected by the following factors.
1. VOLTAGE
When the battery is almost discharged, the voltage will drop
and the fastening torque will be reduced.
2. FASTENING TIME
If the fastening time is prolonged, the fastening torque will
be increased.
However, if the fastening torque reaches the maximum, it
will not increase any more.
3. SCREW AND BOLT
Even though the torque coefficient and class of the screws
or bolts are the same, the fastening torque will differ according
to their diameters. Generally, the larger the diameter, the
higher the fastening torque.
On the other hand, even though the diameter of the bolts or
screws are the same, the fastening torque will differ according
to the torque coefficient, their class and their length.
4. BIT
Failure to use the correct size bit causes a reduction in the
fastening torque.
5. SWITCH
The rotation speed and the fastening torque can be adjusted
by controlling the trigger-squeezing force. The lower the
rotation speed, the lower the fastening torque.
6. LED
LED will be lighted when depressing switch trigger.
BATTERY
The battery (5) for this tool must be charged before you use the tool.
Use the fast charger provided.
The battery is affected by temperature, so do not charge it outside
or in a location exposed to direct sunlight. Doing so will shorten the
charging time and result in less than the full charge.
WARNING!
Do not charge the battery when temperature is below 0°C or
above 40°C.
WARNING!
A battery short-circuit can cause a large current flow,
overheating, burns and even a breakdown.
1.Do not touch the terminals with any conductive materials.
2.Avoid storing the battery in a container with other metal
objects such as nails, coins, etc.
3.Do not expose the battery to water or rain.
WARNING!
Do not store the tool and battery in locations where the
temperature may reach or exceed 50°C.
WARNING!
Do not incinerate the battery even if it is severely damaged or
is completely worn out. The battery can explode in a fire.
WARNING!
The battery and charger are specifically designed for use in
conjunction with one another. Charging should be performed
exclusively with a RYOBI fast charger.
CHARGER
LED FUNCTION OF CHARGER 2601049
See Figure A
LED WILL BE LIGHTED TO INDICATE STATUS OF
Red LED lighted = Fast Charging Mode
Green LED lighted = Fully Charged Battery Pack
Yellow and Green LED Lighted = Control Charge or
Defective Battery Pack.
CHARGING BATTERY PACK
The battery pack for this tool has been shipped in a low
charge condition to prevent possible problems. Therefore,
you should charge it prior to use.
NOTE: Batteries will not reach full charge the first time they
are charged. Allow several cycles (cutting followed by re-
charging) for them to fully charge.
Charge battery pack only with the charger provided.
Make sure power supply is normal house voltage,
240 Volts, 50 Hz, AC only.
Connect charger to power supply.
Place battery pack in charger. See Figure A. Align reaised
rib on batery pack with groove in charger.
Press down on battery pack to be sure contacts on the
battery pack engage properly with contacts in charger.
When properly connected, red light will turn on.
Normally, the yellow and green lights on the charger will
come on. This indicates charger is in control charge mode
and should switch to fast charge mode within 5 minutes.
When charger is in fast charge mode the red light will
come on. If after a period of 15 minutes the yellow and
green lights remain on, remove the battery pack, wait 1
minute and reinsert battery pack in charger. If the yellow
and green lights continue to remain on an additional 15
minutes, the battery pack is damaged and will not accept
charge.
When your battery pack becomes fully charged, the red
light will turn off and the green light will turn on.
After normal usage, 1 hour of charge time is required to
be fully charged. A minimum charge time of 1 to 1-1/2
hours is required to recharge a completely discharged
tool.
The battery pack will become slightly warm to the touch
while charging. This is normal and does not indicate a
problem.
Do not place charger in an area of extreme heat or cold.
It will work best at normal room temperature.
When the batteries become fully charged, unplug your
charger from power supply and remove the battery pack.
